Clairo Yu has always believed in love. A psychology major with a weakness for romance novels, late-night playlists, and happy endings, she's convinced that somewhere out there is someone who will love her exactly as she is. When she meets Toni Corvin—a charismatic basketball captain with a love for books, writing, and fleeting relationships—Clairo thinks she may have finally found that person. For the first time, Toni lets someone in. She texts first. She stays up late talking. She makes promises she seems determined to keep. And despite her reputation, she makes Clairo believe their connection is real. Until one day, it isn't. Without warning, Toni walks away, claiming the feelings are gone. Heartbroken, Clairo spends the entire summer trying to understand how something that felt so genuine could disappear overnight. What she doesn't know is that Toni is fighting a battle of her own—one rooted in a humiliation she suffered years ago, a wound that taught her that loving someone too deeply only ends in heartbreak. Three months later, they return to campus as strangers carrying the weight of everything left unsaid. When Clairo accidentally discovers a collection of letters Toni wrote during the summer—letters filled with confessions she never intended anyone to read—she realizes the truth is far more complicated than she ever imagined. Now, with old fears resurfacing and past wounds refusing to stay buried, Clairo and Toni must decide whether love is worth risking everything for, or if some people are destined to remain unfinished chapters in each other's stories.
